That was enough for a Naga in the Citadel. I lost the Capes in the first wave, bought the Naga on turn 121, got one Angel. Then I upgraded the Naga, picked up a second one, and then another.
In the adjacent zone, from the Watchtower I spot two more Griffin Conservatories. There was a brief skirmish with the opponent; I gathered 9 Angels, was preparing to march towards them, but the opponent surrendered.
